Nice catch. I moved 'ratelimit' after cache in the pipeline and I no longer have any errors.

Thank you for following up to clarify that...

Those warnings are coming from the ratelimit middleware; it also has to come after cache in the pipeline. Ratelimit won't break the proxy in this case, but it also won't do any limiting.

Yes, I have cache in the pipeline before the auth middlewares.

I have fixed an issue with my auth middleware, so my 'UnboundLocalError' has been fixed.

I am still getting the following two errors in the proxy.error log, but everything is working: Jan 10 15:17:34 willswift proxy-server: STDOUT: ERROR:root:ERROR: swift.cache could not be found in env! (txn: tx2d94b78541344672bab6d-0052d0555e) Jan 10 15:17:34 willswift proxy-server: Warning: Cannot ratelimit without a memcached client (txn: tx2d94b78541344672bab6d-0052d0555e)

I have verified that memcache is actually working because my auth system in successfully saving and pulling identities from the 'memcache_client' (as defined here: "memcache_client = cache_from_env(env)"). So everything is working, but the errors are still being reported.

I am on Swift 1.11. A co-worker has Swift 1.13 installed and running in dev and he is not seeing these errors, so maybe this issue has been found and solved already.

Thanks for following up. This is not blocking me...

Also, don't forget to make sure "cache" occurs in your pipeline before tempauth, like so:

pipeline = catch_errors proxy-logging cache ...others... tempauth proxy-logging proxy-server

Ok thank you...

I am able to get tempauth to work, but I am not sure if that means that memcached is working because I get these two errors in my proxy.error file all the time:

Jan 9 16:45:13 willswift proxy-server: STDOUT: ERROR:root:ERROR: swift.cache could not be found in env! (txn: txc75a7ce83d454b479b8c3-0052cf1869) Jan 9 16:45:13 willswift proxy-server: Warning: Cannot ratelimit without a memcached client (txn: txc75a7ce83d454b479b8c3-0052cf1869)

I also have another error, but it might be associated with the auth middleware I wrote. Unfortunately I am not able to see the real error because of the MAXLINES truncation of syslog. :(

memcache_client.set('mauth_creds/%s/%s' % (auth_user, auth_key), (expires, identity), time=env.get('HTTP_X_AUTH_TTL', self.cache_timeout))#012UnboundLocalError: lo

I will see what I can figure out... Thanks for posting back...

Can you please post the final config you used. I am also stuck on this problem and I have tried everything I can think of to get the memcached server and proxy-server to play nice together.

Thanks...
